To all whom it may concern: y l Y.

Be it known that I, JOHN OCONNELL, a citizen of the United States,andresident of St. Louis, Missouri, have invented certain Vnew anduseful Improvements in Heel-Bun nishingMachines, of which the followingis a specification containing a full,clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.f' f l My invention relates to a heel burnishing machine, and the objectof my invention is to construct a machineby means of which the sidesurfaces and bottoms of-shoe heels are simultaneously smoothed off andburnished. E,

To the above purposes, my invention consists of certain novel featuresof construction and arrangement of parts, which will Vbe hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which V Figure 1 is a front elevation of aheelbur-` nishing machineof my improved construetion, the upper portionthereof being invertical Section; Fig. 2 is a vertical section, taken on`the line 2-2 of Fig. 1; Fig. 3 is a plan view of the` front portion ofthemachine; Fig. 4 is a horizontal section taken on the line 4 4 of Fig.1, and parts of the top of the machine frame being in section; Fig. 5 isa vertical-section taken-on the line 54-5 of Fig. 1; Fig. 6 is anenlarged plan view of a modilied 'arrangement'of the bur-` nishingwheels of my improved machine.

Referring by numerals to the accompanying drawings: 1 'designates theframe of my improved machine, in and .upon which the operating parts arearranged, and 2 designates the top of the frame, which is horizontallydisposed, and in the frontiportion of which is formed a pair ofrectangu-` lar openings 3. v Arranged to move longitudinally in eachopening 3 is a block 4, and seated in recesses 5 formed at the outerends of the openings 3 are expansive coil springs 6, the inner ends ofwhich engage upon lugs 7, formed on the outer faces of thefblocks 4.`These springs 6 normally maintain the blocks 4 at the inner ends oftheopenings 3. Y

Formed integral with each block 4 and projecting downwardly from therear side thereof is an arm 8, with the lower end of which is formedintegrala bearing block 9,

and formed through each corresponding pair of blocks 4 and 9 are thevertically alined journal bearings 10,\and arranged for operationtherein are the vertical shafts 11.

Removably positioned on the upper end lof each shaft 11 is a burnishingwheel 1 2, the periphery of which is preferably corrugated, as indicatedby 13. Fixed on each shaft 11, between the blocks 4 andv 9, is a smallpulley 14. The lower end of each vShaft 1lV is slightly reduced indiameter, as indicated by 15, and said reduced lower end vis ournaledfor rotation in a block 16, on vthe yfront and rear sides of which areformed the integral trunnions 17.

l 13l designates a transversely disposed shaft,

which is arranged for rotation in suitable bearings 19, in the lowerportion of the frame 1, and fixed on the center of said shaft is aneccentric 19a. v A yoke 20 is positioned on this eccentric 19a, andextends upwardly therefrom.

21 .designates a horizontally arranged block, the outer ends of whichare bifurcated, and engage the trunnions 17 of the blocks 16.

Formed integral with the center of this block 2l, are the downwardlyprojecting ears 22, between vwhich is pivotally held the upper end ofthe yoke 20.

Transversely arranged'inthe rear portion' of the frame 1 is a drivingshaft 23, and po- Sitioned adjacentV one end thereof is a belt wheel24.A small belt wheel 25 is iixed on the shaft 18 in alinement with saidbelt wheel 24, and, passing around the wheels 24 and25 is a belt 26.

' Extending across the frontof the frame 1 is a cross piece 27, andbolted to the inner face thereof, and projecting inwardly, is a bracket28, in the rear end of which is formed a bearing 29.

' Formed in the top'2 of the frame, between `the openings 3 therein andslightly in front of the same andinalinement with the bear ing 29, is aVbearing 30.

Arranged for rotation in the bearings 29 and 30 is a vertically disposedshaft31, and' fixed thereon is a small pulley 32.

Detachably fixed'onthe upper end of the Shaft 31 is a burnishing wheel33, which is so disposed as that its top surface is arranged injuxtaposition to the under sides of the burnishing wheels 12, and, thetop surface of said wheel is preferably corrugated, as indicated by 34.

Y Transversely arranged in the upper portion of the frame l and to therear of the shafts 11 and 81 is a pair of horizontally disposed shafts35, on each of which are mounted three small pulleys, such as 36. Fixedupon the shaft Q3, to the left of the belt wheel 24 are three similarlysized belt wheels 37. Passing around the central one of these beltwheels 37, over the central pair of pulleys 3G, and forwardly around thepulley 3Q, is a belt 38, and passing around the outer pair of beltwheels 37, over the outer pairs of pulleys 3.6, and forwardly around thepulleys 14, are belts 39.

In the modification shown in Fig. G, I arrange a small burnishing wheel12, in the same plane with and immediately to the rear of the burnishingwheels 12, which smaller wheel 12L has its periphery slightlycorrugated, as indicated by 13a. rlhis small burni ishing wheel isdriven in any suitable manner, and preferably rotates with the sameperipheral speed as does the burnishing wheel 12.

The operation of my improved burnishing machine is as follows: The shaft23 is driven in any suitable manner, and the rotary motion thereof isimparted to the shafts 11 and 31 by means of the belts 3S and 39, whichpass around the corresponding pulleys 1336, 141-., and 32. In thismanner, the shafts 11 and 251 are rotated at a high rate of speed, and,as a result, the burnishing wheels 12 and 83 are rotated. The burnishingwheels 1Q, in addition to rotating, reciprocate vertically, owing to thevertical motion of the shafts 31, which are actuated by the operation ofthe eccentric 19, and its connections, which eccentric is rotated by theshaft 1S driven from the shaft 23 by means of the belt QG. The underside of the shoe heel to be burnished is positioned flat upon the topsurface of the burnishing wheel 33, with the shoe held upright and toone side, as shown by dotted lines in Fig. 3. he operator then graduallymoves the shoe from the leftl to the right and at the same time, bearingdownwardly and rearwardly upon said shoe so as to cause the under sideof the heel to forcibly engage the top surface of the wheel 33, and thesides of the heel to forcibly bear against the peripheries 13 of thepolishing wheels 12. This pressure will naturally cause the wheels 12 tomove apart a slight degree, this being possible owing to the arrangementof the blocks 4l in the slots 3, and the arrangement of the coil springs6 behind said blocks. This movement of course is very slight, and doesnot affect the operation of the belts 39 on the pulleys 14. During thisoperation,

the burnishing wheels 1Q are reciprocating vertically, and thus afterthe shoe heel has been shifted around from one position to an other, theentire outer surface of said heel has been engaged and burnished by theperipheries of said burnishing wheels 12. 'lhe under side of the heelduring this operation has been engaged by the top surface of theburnishing wheel so that when the shoe is removed from the wheels. theentire under side and outer face of the heel is properly smoothed andburnished. For some classes of work, l tind ity advisable to make use ofthe third small burnishing wheel 12, as seen in Fig. 6.

A machine of my improved construction is simple, inexpensive, operateswith a small amount of power, and, by its use. much time and labor issaved in burnishing shoe heels.

The burnishing wheels are all preferably heated while in operation bysuitably located small gas jets. (not. shown.)

I claim:

1. ln a machine of the class described. a frame, a pair of fixedbearings on the frame` a vertically disposed shaft arranged for rotationin said bearings, a burnishing wheel having a corrugated surface carriedby the upper end of said shaft, laterally yielding bearings arranged inthe frame adjacent the shaft, shafts arranged for rotation in saidlaterally yielding bearings, burnishing wheels carried by the upper endsof said last mentioned shafts, the edges of which bnrnishing wheelsoverlie the edge of the lirst mentioned burnishing wheel, means wherebyall of the shafts are rotated, and means whereby the laterally yieldingshafts arc vertically reciprocated simultaneous with their rotation:substantially as specified.

In testimony whereof, ,l have signed my name to this specification, inpresence of two subscribing witnesses.
